を増加させることができる。According to the above invention, the dust sucked from the suction tool is collected from the suction port provided in the direction of contacting the inner peripheral surface of the dust collecting chamber on the side substantially opposite to the side sucked by the electric blower. It is collected in the room. At this time, similarly to the above, due to the suction force of the electric blower, a rotary suction airflow from the intake port toward the suction side of the electric blower along the inner surface of the dust collection chamber is generated in the dust collection chamber, and thus is sucked. The dust rotates on the inner surface of the dust collecting chamber, and it is possible to prevent the dust from adhering to the filter portion having the substantially conical portion for collecting dust located inside the dust collecting chamber, resulting in a reduction in suction force. In addition to being able to suppress, dust is accumulated in the suction direction of the electric blower while rotating in the dust collection chamber, and the dust is compressed by the suction force of the electric blower. A centrifugal force is generated when the inner surface of the dust collecting chamber is rotated, so that the dust is pressed against the inner surface of the dust collecting chamber, and the dust is further compressed, so that the dust collecting amount can be increased.

結果的に吸込み力の低下を抑えることができる。In FIGS. 5 and 6, when the electric vacuum cleaner is operated, the dust sucked from the suction device is provided with the suction port provided substantially on the opposite side of the dust collection chamber 10 to the side where the electric blower 9 sucks the dust. The dust is collected from the inside of the dust collection chamber 10 through the inside of the intake pipe 20 having a substantially cylindrical shape. At this time, if the opening of the intake pipe 20 is opened tangentially to the inner surface of the dust collection chamber 10, the suction force of the electric blower 9 causes the electric power to flow from the intake port 15 along the inner surface of the dust collection chamber 10. A rotary suction airflow toward the suction side of the blower 9 is generated inside the dust collection chamber 10. Therefore, the dust sucked from the intake port 15 passes through the intake pipe 20, and then rides on the rotating air flow to rotate the inner peripheral surface of the dust collection chamber 10 toward the suction direction of the electric blower 9. It is sucked vertically and substantially horizontally. According to this principle, the sucked dust rotates on the inner surface of the dust collecting chamber 10 as shown by the arrow in FIG. 6, so that the filter portion 13 having the substantially conical portion for collecting dust is located inside thereof. Can suppress the adhesion of dust,
As a result, a decrease in suction force can be suppressed.

Moreover, since the pre-filter 12 is rotatable, the dust sucked into the dust collecting chamber 10 is accumulated on the suction side of the electric blower 9, but the dust having a relatively small mass also has a centrifugal force. The size is small and the electric blower 9 is often sucked by the filter unit 13 to which the electric blower 9 is sucked. In that case, relatively coarse dust is collected by the mesh portion 23 of the pre-filter 12, and fine dust passes through the mesh portion 23 and is collected by the main filter 11. By repeating this, dust is firmly attached to the surface of the pre-filter 12. By rotating the pre-filter 12 in that state, the dust adhered to the mesh portion 23 rubs against each other, and as a result, the dust adhered to the mesh portion 23 can be removed, so that the suction force can be recovered.
